---------------------------------
+1
I would also like to see this feature as it will significantly help overall
cluster performance for known "hot" URI"s.

> Key: TS-2184
> URL: https://issues.apache.org/jira/browse/TS-2184
> Project: Traffic Server
> Issue Type: Improvement
> Components: Cache, Clustering
> Reporter: Scott Harris
>
> With proxy.config.http.cache.cluster_cache_local enabled I would like cluster
> nodes to store content locally but try to retrieve content from the cluster
> first (if not cached locally) and if no cluster nodes have content cached
> then retrieve from origin.
> Example - 2 Cluster nodes in Full cluster mode.
> 1. Node1 and Node2 are both empty.
> 2. Request to Node1 for "http://www.example.com/foo.html";.
> 3. Query Cluster for object
> 4. Not cached in cluster so retrieve from orgin, serve to client, object now
> cached on Node1.
> 5. Request comes to Node2 for "http://www.example.com/foo.html";.
> 6. Node2 retrieves cached version from Node1, serves to client, stores
> locally.
> 7. Subsequent request comes to Node1 or Node2 for
> "http://www.example.com/foo.html";, object is served to client from local
> cache.
